CLAIM:
Examine the system model below, which shows a car moving along a track at two different points in time. Assume there is no friction between the car and the track.
In the before image, a car is moving along a track at a constant speed towards a motionless wheel.
In the after image, the car has contacted the wheel, which begins to spin. The car continues to travel along the track at a slower speed.
THE QUESTION:
Which Claim below best explains what causes the wheel to spin after contact with the car?
1 - The wheel stops spinning because kinetic energy was transferred from the car to the wheel.
2 - The wheel begins to spin because kinetic energy was transferred from the car to the wheel.
3 - The wheel pushes the car, causing it to go faster
4 - The wheel begins to spin because kinetic energy was transferred from the wheel to the car.
Answers
Answer:
The wheel moved because of the car.

On the side and top of diagram B, you are given 4 different options for clothing and 3 for the color. This chart shows all the possible combinations as well, meaning that option B is right too.
On top of this, you can also notice that both diagrams A and B have the same labels, just moved around.

The radius and the diameter of the circle are 11 cm and 22 cm respectively.
Step-by-step explanation:
The radius of a circle is a line segment extending from the center of a circle or sphere to the circumference or bounding surface, while the diameter of a circle is a straight line passing from side to side through the center of a body or figure, commonly a circle or sphere. Since the diameter goes entirely across the circle while passing through the midpoint - or center - of a circle and the radius only goes from the edge to the midpoint, that means the diameter is twice as big as the radius. In this example, the radius is already given to you, which is 11 cm, based on the image. Using this, you can figure out the diameter of that circle would be [tex]11 * 2[/tex] or 22 cm. So the radius of the circle is 11 cm, while the diameter of the circle is 22 cm.

Kelly paid $45.36 for a sweater that was on sale for 25% off the original price. She paid 8% sales tax on the sale price.
What was the original price of the sweater, in dollars?
(Please explain your answer if you want, I would appreciate and give brainliest if you do so.)
Answers
The original price of the sweater, in dollars is $52.1648.
What is meant by percentage of a value ?Percentage of a value is defined as the ratio of the value expressed in terms of fraction of 100.
Here,
Percentage of sales tax = 8%
Amount paid as sales tax, P(tax) = 8% of 45.36
P(tax) = 0.08 x 45.36
P(tax) = $3.6288
So, the remaining amount = 45.36 - 3.6288 = $41.7312
Percentage off on the price = 25%
So, the price paid, P' = 0.25 x 41.7312
P' = $10.4328
Therefore,
Original price of the sweater, P = 41.7312 + 10.4328
P = $52.1648
Hence,
The original price of the sweater, in dollars is $52.1648.
